The invention relates to a supporting frame for a petroleum pipeline. The supporting frame comprises a base, support plates, lower hoop bodies, upper hoop bodies, a vertical supporting plate and mounting plates; the two mounting plates are symmetrically arranged on the base and are connected to the base in a sliding mode; a plurality of angle brackets are arranged at the two ends of the mounting plates and are fixedly welded to the mounting plates; first bolts are arranged on the lower parts of the angle brackets; and a plurality of first bolt holes are formed in the positions, corresponding to the first bolts, of the side surface of the base. According to the supporting frame, the mounting plate capable of sliding on the base are arranged, a pipeline fixing ring is divided into four parts, the distance between the mounting plates and the size of second notches are adjusted so that a device can be applied to an oil conveying pipe within a certain range, and therefore the applicabilityof the device can be improved, and popularization and application of a pipeline support can be facilitated; and the support plates are arranged so that the bearing capacity of the vertical supportingplate can be improved, in addition, the inclination angle between the support plates and the vertical supporting plate can be adjusted through second bolts so that when the stress of the pipeline support is too large, the support can be adjusted to increase the supporting force, and the stability of the oil conveying pipe can be guaranteed.
